Application filed-May 12; 1921. Serial No. 469,013.

To all whom it may concern: Be it-known that we, Fonnns'r E. BING- iran and THOMAS 'TOMLINSON citizens of the United States residing at how Bedford, in thecounty of vl3ristol'and State of Messachusetts haveinvented certain new and useful Improvements in Spoofin -Machine Tension Devices, of which the following is a s ecification. r

his invention relates to certain new and useful improvements in tension devices for spooling machines, and the primary object thereof'is to provide a tension device which utilizes a, freely mounted weighted element, such as a ball, which functions to tension the thread by bearing "thereon, and a. device in which balls of varyin sizes or weights can be easily and quicfrly substituted in order to var the tension exerted thereby on the thread V y A further object of the invention is to provide a device of this kind that is formed to free itself of'the accumulation of any foreign matter, such as waste, fly or dirt.

The invention further aims to provide a device of this type which is of simple and economical construction and which is devoid of any moving parts which require lubrication.

Further and other oh'ects will be later setforth and manifested in ,the course of the following specification.

In the drawings: Figure 1, is a; side elevation of the invenon applied to a spooling machine;

Figure 2, is' an enlarged side elevation of the invention;

Figure 3, is a top plan view, and Figure 4, is a section on line lt of Figure; 3 illustratin use of balls of varying diameters.

In proceeding in accordance with the press, ent invention, a body is employed which has' aforked end, Qequipped with a, set screw 3, to receive and be clamped ont-o agrodg A, of the spooling machine, which rodfha's vertical rising and'falling movements and is interposed as usual between the-cop B and the spool C. At its outer o'r-jgfr'ee portion, the body is formed with anofiset 4 which is formed with a deep. ical shaped cup 5, the interior walls :01 hich are formed perfectly straight. the cup having an open top and an open bottom, the latter of sufficient size so as',tofall'ow any fly, dirt or gin dotted lines the waste to .freely gravitate t'herethroug-h to thus maintain the cup in aclean cond tion. The outerside of the cup is formed with alongitudinal slot '6 whichextends' through the top and bottom thereof, andisafurther forme with a pair. of guidearmsor fingers I Tand 8 that flank the slot 6. The arm 7* is straight, while the arm 8 is preferably curved outwardly away from the arm 7 to thus form an outwardly fia rin mouth for the slot 6 and allow of the tiread bein more easily introduced into the slot and therethrough the cup interior.

Freely mounted within the on is a. ball 9 of suitable weight and and which, through the action of gravity.,' bears on and holds the thread T, in fric tional engagement with the interior 'all of the cup. Obviously balls of various weights and diameters can be easilyls fubjsti- 7,6 tuted by merely lifting same out of and dropping them into the cup. i In threadin the device, the thread is I simply passed between the arms 7Tancl 8, and when it begins to move it will draw itself under the ball. .Consequentlndt is unnecessary to remove the ball when it'is desired to thread the device.

The device can be made of cast metal and thus can be economicallyproduced andbyvirtue of the screw 'the body may beadjusted with respect;v to the rodA so that the thread will; en age the cup interior throughoutythe depti'thereof to thus effect uniform drawi on-the thread. v

The cupis madedeep and flared to'a de gree toga-110w balls of varying diameters to be usedfcind still not move out of the-cup as showii in Figure 4.

H hat is claimed is "1.1m a tension device for spooling ma ;,:chines, a body having a forked end provided j with a set screw for adjustable. attachment to the vertically rising and falling rodfof a spooling machine, said body being formed 10 with an offset adjacent its outer end portion, said offset being provided with a cup of conical interior form, said cup having an opentop and bottom and havinga 1on gitudinal slot on its outer side and having a pair of arms extending outwardly therefrom and arranged on opposite sides of the slot, one of the arms being curved outwardly to form a flaring mouth formation leading into the slot, and a ball freely placed in interior diameter ZQY chines, a body, meens on one end of the ,body to secure same to the maohme, a,u offset onthe opposite'end of the body having a on of conical interior form, the-cu heing 1eld hy'the offset .to one side 0 the body so that the thread W111 pass along a 7 sideof the body without engaging the 7. same. the cuphtving a, thread mlet, and a" ball loosely placed in the cup.

: engage about the falling andrising rod of 3.111 a tension device 'for spoofing machines, a body having one end .formed to the spooli-ng machine, means to adjustably secure said end to the rod so as to enable the body to be pivoted about the rod and then rigidly affixed thereto, an offset 011 the opposite-end of thehod havin a on of conical interior form, t e cup dieing held by the oflset to one side of the'body so that the thread will pass along 'a'side of the body without en aging the some, the cup having a thread in at, and a; hall loosely placed in the cup.

In testimony whereof we affix our signatures. I
